upon the stein 32 that the distance between tliein Will be A`greaterthan the ydistance between the valve seats 29 and 30 With the resultthat both valves may be simultaneeusly in open position as shown in Fig.

oiE the drawings, to provide for the passage et liquid fuel from thesupply pipe 2l into the lloat chamber G, or either valye may enhure itsseat so as to prevent the loiy oi fuel. The salve stein 32 extends belowthe head and through an opening' formed in a plug 37 which is adjustably'threaded into the levier eiid ot the iieel di, and a spring is fittedto this downward eXtension the valve stein and bears at its lower endinst the said plug 37 and at its upper end against one of vthe nuts 36,Thus the tendency et the spring` 38 is to Shift the Valve bodilyupwardly so that the head Will engage the seat 30 and prevent thepassage ofi? liquid fuel. into the float chamber, and the tension ofthis spring inajgf be varied by adjusting the plug 37. In order that theliquid ituel after passing' the valve 35, may have unrestricted passagei'ioin the necl 3l of the valve casing- :26, the Wall of the neck is'torined with vertically extending slots 39, as clearly shown iii Figs.5 and 6.
